AUTOMATIC PILING DEVICE FOR PRINTING-PRESSES.

SPECIFICATION forming part of Letters Patent No. 273,052, dated February2'7, 18 83.

Application filed June 5, 1882. (N0 model.)

: Printing-Piesses, of which the following is a specification, referencebeing had to the accompanying drawings, of which- Figure 1 is a plan oftheinvention, showing the position of the piling mechanism, with the flyof the printing-machine in a horizontal position, as casting a sheet ofpaper upon the delivery-board in an oblique position. Fig. 2 is a planthereof, showing the position of the de vices when the fly has ascended,ready to take the next sheet from the press, the sheet being broughtinto the proper position, or squared, by the action of the pilingmechanism. Fig. 3 is plan similar to Fig. 1, illustrating a modificationin the arrangement of a part of the squaring device useful under somecircumstances, as hereinafter set forth. Fig. 4 is a front end elevationof the apparatus when the parts are in the same relative position asthat of Fig. 1. Fig. 5 is a section upon the line m, Fig. 2.

Like letters of reference, where they occur in the several figures,indicate corresponding parts.

The nature of this invention is a combination of devices the movingparts of which are actuated by the vibrations of the fly of a powerprinting-press, whereby the sheets of paper are caused to be evenlypiled or squared upon the delivery-board of the machine.

It consists in one or more bars or levers arranged to slide in groovesin the delivery-board of a printing-machine by the action of the fly,which bars are provided with upright adjustable plates, in combinationwith fixed stops secured to the delivery-board, one or more of whichstops are in a plane parallel with and one or more in a plane at rightangles to the direction of movement of the said sliding bars, in amanner that eachand every sheet of paper, when pressed forward by theupright plates upon said bars, will strike against said stops.

it consists, also,in the combination, with the said sliding bar or barsand the upright plates adjustable thereon, of a similar baror bars,withlike plates at right angles with the first-mentioned bar or bars, whichis or are caused, by the same impulse of the fly actuating the latterbars, to slide at right angles thereto, and thereby press against andsquare the ends of the sheets at the same time thatthe sides thereof arebeing brought into the required position, as hereinafter to bedescribed.

.I have deemed it unnecessary to show other parts of a. printing-machinethan thefly and deliveryboard as seen in the drawings, as theirconnection and function are well understood by those familiar withprinting-machines as nsually made.

Referring now to the accompanying drawings, D is the delivery-board. Fis the usual vibrating fly, which in the position shown by Figs. 2 and 5receives the printed sheets of paper as they pass from theprinting-rolls, and, rotating to the position of Figs. 1. 3, and 4,delivers the same upon the board D. VVithout a suitable piling orsquaring device the sheets will be unevenly piled-that is, their edgeswill not register-as one is superimposed upon the others by the fly. Inthe present instance the latter is provided with acounterbalance-roller, R, pivoted to arms 2, which extend below thebearings upon'which the fly turns.

B B are bars or levers lying in grooves in the top of thedelivery-board, and held therein by means of the plates 19. When the flyvibrates backward and upward-that is to say, from the position seen inFigs. 1, 3, and 4 to that seen in Figs. 2 and 5to receive the sheet fromthe printlngcylinder, the counter-balance impinges against studs O uponthe bars B B, and thereby propels the latter forward a certain distance.When the fly descends to deliver the sheet S the bars B B are made torecoil back a suitable distance by the stress of a helical spring, H,Fig. 5, beneath the delivery-board, one end of which spring is securedto a pin, it, and its other extremity to a stud, a, which is fixed tothe under side of the bar and extends through a slot in the board D, asshown in Fig. 5.

E E are vertical plates, attached to angleplates G, which are adjustablelengthwise of the bars B B, and fixed to the latter at the desiredpoints by means of a thumb-nut, a, in connection with a threaded bolt,1), which works in a longitudinal slot in said bars. These. verticalplates are also adjustable with said angleplates by means of the saidnut and bolt, so that either may be inclined so as to stand at an angleto the other, as in Fig. 3.

J J are stop-plates secured to the delivery board, toward the front endof the same, by means of the screws 0, which pass through the slots (1,whereby the plates may be readily adjusted to the desired position. J Jare similar stops at the side, in a plane at rigl'itangles to thatoftheend stops, J. The function of these side and end stops is to limitand gage the position of the sides and ends of the sheets ofpa per whenthe latter are snit'ted by the action of the plates E E on the slidingbars, as hereinafter described. In order to secure the proper movementof the sheets-for instance, toward the left and at the same timeforward--one oi" the plates, E, is canted to the left, as shown in Fig.3, and there secured. Now, when the sheet S is laid by the fly upon thedelivery-board in front of the plates E E, the inclined side of thelatter, Fig. 3, striking the corner of the sheet as the bars B B areadvanced by the fly, as before described, forces the sheet forwardtoward the stops J and at the same time sidewise toward J; and the sideofthe papercoming into contact with the plate E, which remains at rightangles to the plane of movement of the bars, prevents it (the sheet)from being canted too far around by the action of the iiiolined plate E.It will be observed that the plates E E are slotted vertically, and alsothe stops J'are placed so as not to obstruct the movement of the tly asit approaches the delivery-board.

The toree'oing-described arrangement of my invention is useful moreespecially when the sheets of paper are of comyaratively smalldimensions. Under other circumstances, with larger sheets, it ispreferable to make use of a sliding bar, B as shown in Figs. 1 and 2, inconjunction with the bars B B, which bar B is caused to move at rightangles to the others in order to square the ends and sides of the sheetssimultaneously. This cross-bar is provided with an adjustable plate, Esimilar to E and E. Bar B crosses beneath bar B, as

seen in Figs. 1 and 2. In order to obtain the requisite movement of thesamethat is, so that its plate E shall press one end of the sheets whileplates E E are pressing the side thereof-I provide the ra-clrand-piniondevice shown. This consists of the cogs or teeth at in the outer edgesof bars B B toward the ends of the same, which engage with the cogs of asmall wheel, W, rotating on the pin a, which is fixed to thedelivery-board. WVhen the bar B is advanced by the fly and retracted bythe spring H, wheel W is caused to rotate, which of course imparts amovement to the bar B forward or back corresponding to that of B.

In Fig. l the sheet S is shown as delivered obliquely, and in Fig. 2 assquared by the operation of the devices described. In thisinstance,

when the crossbar is used in conjunction with the others, it isunnecessary to incline any of the plates on the bars, and in such casethe stops J and J may usually be dispensed with Without much, it any,disadvantage, as the positive push of the squaring-plates E E E at theside and end of the sheet will cause the latter to take the sameposition as those preceding it.

It is obvious that the fly may be provided with suitable projections,located so as to impinge against the studs (J, in lieu of the coun-Qters Patent l. Inapaper-slieet=pilingdeviceforprintingmachines, thecombination of the fly, the bats B B, having push-plates E E,longitudinally and pivotally adjustable on said bars, and the studs C,the counter-balance 1t, and stops J J, all constructed and operatingsubstantially as and for the purposes set forth.

2. In a paper-piling device, the fly and its counter-balance, thedelivery-board, the bars B B, with plates E E, actuated by the fly andspring H, and the crossbar 13*, with plate E all constructed, combined,and operating substantially as and for the purposes shown and described.

3. The combination of the bars Band B provided with the plates E and Erespectively, both of said bars having the cogs m, with the commonpinion 7, arranged in relation to said bars substantially as and for thepurpose specified.
